Description

Assembling corrugated web interlock girder steel
Technical field
The present invention relates to a kind of assembling corrugated web interlock girder steel, belong to the architectural shape technical field.
Background technology
At present, the assembling type steel structure system is the important directions of system of steel residential structure development.Traditional housing building of steel-structure has adopted a large amount of scene welding when constructing, speed of application is slow, and seriously polluted to environment the most important thing is that the quality of weld seam should not be controlled, have a strong impact on the security performance of building, the assembling type steel structure system has overcome the shortcoming of traditional steel house effectively.In the assembling type steel structure system, the on-site consolidation of Liang Heliang is a problem that needs primary study.
The section steel beam that can adopt in similar field comprises hot rolling i iron, hot rolled H-shaped, welded H section steel, hot-rolled square steel pipe, welding box-shaped beam and channel-section steel etc.
When H shaped steel such as hot rolling i iron, hot rolled H-shaped and welded H section steel are used in the assembling beam, can only be connected with the edge of a wing of bolt to beam by adopting cover plate, not only waste steel, and it be also poor to connect effect, influence the holistic resistant behavior of beam.
When the girder steel that hot-rolled square steel pipe, welding box-shaped beam equal section are closing forms carries out the assembly unit of Liang Heliang, can only be connected with the edge of a wing of bolt to beam by adopting cover plate, the web part can't connect, and namely wastes the stress performance that steel influence beam again, and beam can not be played one's part to the full.
In existing assembling type steel structure system, what adopt usually is that two channel-section steels carry out assembly unit, and the web butt joint of two channel-section steels connects by bolt, forms assembling H shaped steel.But in this connecting method, shearing is to pass to web by bolt, and web is plain plate, so the steel using amount of required bolt number and web is very big.
This shows, traditional Steel section member is used in effect is not very desirable among the assembling type steel structure, not only influence the stress performance of member, and need to consume a large amount of steel, produce unnecessary waste.So it is imperative to create the novel primary structure member that is applied to the assembling type steel structure system.
Summary of the invention
The present invention proposes a kind of assembling corrugated web interlock girder steel that belongs to the architectural shape technical field, the object of the present invention is to provide a kind of with low cost, the assembling girder steel of the assembling type steel structure system that is applicable to that stress performance is superior.
Technical scheme of the present invention is as follows:
A kind of assembling corrugated web interlock girder steel is to be formed by bolts assemblies by two wave groove girder steels, wherein, the web interlock of two wave groove girder steels butt joint, connection is assembled by bolt by the place at web; Described wave groove girder steel, its section shape of the mouth as one speaks are by the top flange, and web and bottom flange are formed, and described top flange is parallel with the bottom flange, and described web is vertically between top flange and bottom flange; The section of described web is the ripple that even or inhomogeneous periodicity repeats, and this ripple section is rectangle waviness curve, trapezoidal waviness curve, wedge shape waviness curve or sine curve; Have bolt hole on the described web, be used for connecting bolt; Described top flange and bottom flange are steel plate, and parallel with web in a steel plate limit is wavy curve, and the shape of waviness curve is identical with the ripple section configuration of web; Described web is positioned over the place, waviness curve limit of top flange and bottom flange, and the ripple section of web coincide with the waviness curve limit of top flange and bottom flange and links to each other.
Described rectangle waviness curve is arc chord angle rectangle waviness curve, and described trapezoidal waviness curve is the trapezoidal waviness curve of arc chord angle, and described wedge shape waviness curve is arc chord angle wedge shape waviness curve.
The inclination angle of the trapezoidal oblique line section of described trapezoidal waviness curve, arc chord angle rectangle waviness curve is 20 °-90 °; The inclination angle of the wedge shape oblique line section of described wedge shape waviness curve, arc chord angle wedge shape waviness curve is 20 °--90 °.
Be respectively the single face fillet weld between described web and top flange and the bottom flange.
The ripple density of described web and height can change according to force request.
Described arc chord angle rectangle waviness curve, the trapezoidal waviness curve of arc chord angle and arc chord angle wedge shape waviness curve adopt the numerical control bending technology to make, and sine curve adopts numerical control roll-in technology to make.
Beneficial effect: the present invention proposes a kind of assembling corrugated web interlock girder steel that is applicable to the assembling type steel structure system, improved the stress performance of prefabricated member widely, compare with traditional assembling type steel structure system in the assembling girder steel, the present invention has following advantage:
Steel beam web plate after the assembling is the assembling corrugated steel, can effectively utilize rigidity outside the good plane of corrugated steel, anti-flexing supporting capacity and higher fatigue strength, compare with the plain plate that channel-section steel is assembled into, deformability all is significantly increased outside its shear-carrying capacity and anti-under the identical situation of thickness.Use it for the building structural steel beam and can under the prerequisite that guarantees shear-carrying capacity, save steel in a large number.
Girder steel after the assembling holds the interlock shape, shearing bearing capacity in the plane of effective increase assembling girder steel, shearing in the plane of traditional assembling girder steel relies on bolt to bear and transmit, the present invention relies on the interlocking of girder steel to make whole girder steel bear shearing in the plane, improves the shear resistant capacity of assembling girder steel effectively.
Therefore, adopt assembling corrugated web interlock girder steel of the present invention can bring into play above-mentioned two kinds of technical advantages simultaneously, compare with other like products, its mechanical property is significantly increased, and the thickness of the edge of a wing and web all can reduce, and can significantly save rolled steel dosage.Simultaneously, in the assembling corrugated web interlock girder steel that the present invention proposes, it is relations of having optimized to a greater extent between section mechanical property and the product steel using amount that section makes up maximum characteristics, makes it more be tending towards rationalization and scientific.Therefore, the present invention has good stress performances such as high-bearing capacity and high rigidity, is a kind of very good structural shapes material.The present invention adopts full automatic welding connection technology and professional positioning tool anchor clamps, can guarantee the accurate location between web and the edge of a wing, and the seam track unanimity realizes standardization easily, can realize many large-scale production, effectively enhances productivity.
Compare with traditional assembling girder steel, the present invention has improved the supporting capacity of girder steel significantly, has reduced steel using amount, has reduced construction costs, can realize large-scale industrial production and on-the-spot quick assembled type simultaneously, reduces construction period.
